EXTENSION-STOVEPIPE.

To all whom it may concern:

Be it known that I, HEBER K. HANSEN, a citizen of the United States,residing at Logan, in the county of Cache and State of Utah, haveinvented a new and useful Extension-Stovepipe, of which the following isa specification.

The invention relates to an extension stove me.

The object of the present invention is to provide an extension stovepipe or an extensible connection, adapted to enable common piping to bereadily adjusted to fit any space between a stove and the angle or elbowleading to the flue without cutting the pipe sections.

WVith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to with out departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a longitudinal sectional view of anextensible stove pipe, constructed in accordance with this inven tion.Fig. 2 is a transverse sectional view, taken substantially on the line00-51: of Fig. 1. Fig. 3 is a detail perspective view of thelongitudinal ratchet bar. Fig. 4 is a similar view of the combined guideand catch.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The extensible stove pipe or connection comprises two telescoping pipesections or members 1 and 2, the upper pipe section or member 1 beingprovided with a tapered crimped end 3 to fit the plain end of anordinary stove pipe (not shown.) The other section 2, which consists ofa plain cylindrical pipe, is adapted to receive the tapered or crimpedend of an ordinary stove pipe (not shown.) The pipe sections or members1 and 2 are slidable on each other to vary the length of the extensiblestove pipe or connection to enable ordinary piping to be readilyadjusted without cutting to suit the distance or space between a stoveand the angle or elbow leading to the stove pipe hole or open- I ing ofa chimney or flue, and the said sections Specification of LettersPatent.

1 and 2 are adjusted by means of a longitudinal ratchet bar 4 and atransversely disposed combined guide and catch 5. The

ratchet bar, which is secured at its upper end 6 by rivets 7, or othersuitable fastening devices to the tapered or crimped upper end 3 of thepipe section 1, extends downwardly to a point adjacent to the lower endof the said section 1, and it is provided at intervals with ratchetteeth 8, which are shouldered at their lower edges. The lower edges ofthe teeth 8 are inclined to enable them to hook over the combined guideand catch 5, whereby the upper section 1 is locked against downwardmovement.

The combined guide and keeper, which may be constructed by stamping itout of a strip of metal, or in any other preferred manner, consists of acurved intermediate portion 9 and attaching angle arms 10 and 11,secured by rivets 12, or other suitable fastening devices to the lowerpipe section 2 near the upper end thereof. The attaching arms 10 and 11are approximately L-shaped, and they off-set the intermediate curvedportion 9 from the inner face of the pipe section 2, as

clearly illustrated in Fig. 2 of the drawing.

The connecting portion 13 of the arm 10 is arranged at an inclination toform a catch, and its upper end is arranged to be engaged by the teethof the ratchet bar, as clearly illustrated in Fig. 1 of the drawing. Theratchet bar, which extends through the space 14 between the curvedportion of the combined guide and catch and the stove pipe section 2, isdisengaged from the inclined connectin portion 13 by raising the pipesection 1 an slightly rotating the same in the direction of the arrow inFig. 1. This will ermit the sections to be adjusted longitudina ly oneach other to make the extensible stove pipe or connection the desiredlength, and the sections or members are locked by a reverse limitedrelative rotary movement to carry a tooth of the ratchet bar intoengagement with the inclined connecting portion 13. The inclinedconnecting portion 13 extends upwardly and'inwardly from the lower edgeof the arm 10, and the weight of the upper section and the pipingsupported by the same will maintain the ratchet bar firmly in engagementwith the inclined connecting portion 13 of the combined guide and catch.The free lower end of the ratchet bar is angularly bent to form an.inwardly or upwardly extending hook-shaped sto 15, which extendslaterally or horizonta ly and then upwardly. The hook-shaped stop 15 isarranged to engage the lower edge of the combined guide and keeper tovprevent the sec- I tions of the extensible stove pipe from becomingseparated.

The combined guide and catch are located wholly within and are concealedby the sections of the extensible stove pi e, and they in nowiseinterfere with the siding of the sections on each other, when theratchet bar is out of engagement with the inclined engaging portion 13of the combined guide and catch.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is z- 1. An extensible stove pipecomprising two telescoping pipe sections, a longitudinal ratchet memberlocated within and secured to one of the sections, and an interiorlyarranged combined guide and catch fixed to the other section andreceiving the ratchet bar and arranged to be engaged with the teeththereof by rotating one of the sections.

2. An extensible stove pipe comprising two telescoping pipe sections, alongitudinal ratchet bar secured at one end within one of the pipesections and provided at the other end with a stop, and a combined guideand catch receiving the ratchet bar and arranged to be engaged with theteeth thereof by rotating one of the sections, said guide and catchbeing also adapted to be engaged by the said stop. 7

3. An extensible stove pipe comprisin two telescoping pipe sections, alongitudina ratchet bar secured at one end within one of the pipesections and provided at the other with an inwardly extending hookforming a stop, and a combined guide and catch receiv ing the ratchetbar and arranged to be engaged with the teeth thereof by rotating one ofthe sections, said guide and catch being 4. An extensible stove pipecomprising,

two telescoping sections, a ratchet bar se' cured to one of thesections, and a combined guide and catch secured to the other sectionand consisting of attaching arms and an intermediate connecting portion,one of the arms being arranged to be engaged with the teeth of theratchet bar by rotating one of the sections.

5. An extensible stove pipe comprising. two telescoping sections, aratchet bar secured to one of the sections, and a combined guide andcatch consisting of a curved intermediate portion spaced from the othersection, and terminal arms connecting the curved portion with the lattersection, one of the arms being provided with an inclined portionarranged to be engaged by the teeth of the ratchet bar.

6. An extensible stove pipe comprising two telescoping sections, aratchet bar secured at one end to one of the sections and having itsother end bent to form a hook-shaped stop, and a transversely disposedcombined guide and catch consisting of a curved intermediate portionspaced l'rom the other section of the extension stove pipe and confiningthe ratchet bar and arranged to be engaged by the hook-shaped stop ofthe same, and angle arms connecting the intermediate portion of thecombined guide and catch with the latter section of the extension stovepipe, one of the said arms being provided with an inclined portionarranged to be engaged by the teeth of the ratchet bar.

In testimony, that I .claim the foregoing as my own, I have heretoaflixed my signature in the presence of two witnesses.
